+1 on lower tier intel mini PC. I have a slew of different boxes by Beelink, Intel, and Asus. The N95 box I bought from Beelink (basically an N100) has been one of the most impressive for being so low power, and yet handling the wealth of services I’ve been running on it (with a lot of overhead yet).
Step 1: Get tested for sleep apnea. If you have it, snoring is the least of your worries. Don’t skip this step.
Otherwise, sleep on your side, elevate your upper body (Amazon sells wedge pillows).
If you are certain you don’t have apnea, you can also try a chin strap. Just be sure any chin strap you buy pulls your chin up, not back, as this will A: Obstruct breathing, and B: cause major jaw pain.
